JSMHarish.. Reur Oil-Rig Facility. There is an error in your Fault-Chart! Contact me if you want details. Phil Corso

Bilal.Bhatti The Trend data is not in any of the 6 jpg's.! Phil Corso

Bilal.Bhatti... WTF has pointed out why you should have started a New Forum. In this case one must go thru unrelated pages before addressing your problem. Leads to error, especially at my age! Thanks WTF, Regards, Phil Corso

Bilal.bhatti ... Do you have monitored data over a period of time, similar to those provided by the originator of this topic, JSMHarish. I mean like kW, V, A, Pf, and component vibration, as well as Engine data like RPM and fuel consumption-rate! Finally service, Marine or Land-based? Regards...

Rohit... (Excuse my informality) Having worked on a cruise ship for about a year, I know how busy the crew is. So take as much time as you need. The info I need to close my Project File are the PF Nameplate Rating of the 2 Generators, not the "Indicated" ones! In closing, if you ever find...

Robert Singh.. Here is a copy of how speed (RPM) is monitored in a Nuclear Plant: " When the engine achieves 125 rpm, the LSR relay is picked up. When the engine achieves 800 rpm (900 rpm rated speed), and the HSR relay is picked up along with the TD3 relay (a time delayed relay set for 7...

Rohit Singh... I suggest you check the RPM sensor located on the engine! Regards, Phil Corso

Rohit Singh... 1) Variation is about 2% which isn't much! But, does problem occur only when the Gensets are paralleled? 2) How old are machines? 3) You provided Name-Plate ratings as kW, V, A, RPM... What is power-factor rating shown on Nameplate? Regards, Phil Corso

JSMHarish... My program, using your Fault-Chart Data, showed the following: At time, 16:07, Engine1 started having speed control problems resulting in reduction of output-torque, but without speed-change! Although Generator1 was synchronized with the others, a decrease in the Engine's...

JSMHarish... In order to complete the program that will prove the cause of the problem I need to know the following: 1) What is the size and distance of the feeder cables between the Generator and the AC Bus? Regards, Phil Corso ([email protected])

Blake James... It's been a while since you brought your paralleled Genset problem to this forum. Hopefully, you have solved it. If not I can still help! I have produced an Excel program that simulates the situation, and can provide it to this Forum. If are interested contact me at...

WTF? Adeus a voce tambem!

To all: A while back I was accused of being "very angry". That term is silly! But, I am disappointed that several men supposedly educated and/or trained in trouble-shooting Gen-set operation don't use the basic terms like, RMS VALUES, PHASORS, POWER properly. Many have used the terms Volts...

ContolsGuy25... My opinion is... the Diesel-engine is at fault. Your opinion is... Generator electrics are at fault. Only one person can resolve it... JSMHarrish. So, JSM... you are up ! Regards, Phil Corso

Blake James... The numbers you provided in Msg 8 indicate two problems to me: 1) The Genset kW outputs are less then 40% of their rated capacity ! Thus, being operated underload, a condition which can severely damage the Diesel-Engine, and shorten it's life service. 2) Amperes are not...

JSMHarrish... The problem is not Electrical! It's Mechanical! In my message #14, I said the gensets are underloaded. I suggest you take a look at the Diesels! Phil Corso
